Abstract

The present study was carried out at Instituto de Zootecnia, SP, in order to evaluate chemical composition of silages made from green and vvilted herbage of elephantgrass (Pennisetum purpureum Schum.) cv. €˜Guaçu€™. Silages were made from both fresh and wilted herbage, whole and cliopped plants, with whole plants being dehydrated for 24 h under field conditions. Chopped herbage was wilted in the sun for 4 h on a brick-floored area. Experimental silos were 150-L plastic drums. Treatments consited of ali possible combations of three forage ages (maturities) and three types of forage (thus a 3 x 3 factorial).The wilting methods, did not improve quality of Guaçu elephantgrass silage vvhen forage DM concentration was higher than 21.2%. Ali the silages were classified as being well preserved, when parameters like silage density and its composition in terms of pH. organic acids and amoniacal nitrogen were considered.
